Objective: To investigate the effects of uncorrected nasal septal deviation on the pyriform aperture (PA) dimensions, the upper anterior face height (UAFH), and the anteroposterior length of the maxilla (LM) of adult patients.
Methods: The study included 150 patients (104 males, 46 females; 18-63 years) who had paranasal sinus CT. The study population consisted of 51 patients with anterior nasal septal deviation (NSD) (group I), 72 patients with posterior NSD (group II) and 27 patients with no NSD (group III). By using multi planar reconstruction (MPR) technique, on coronal plane the width of PA (PAW), the right and left maxilla spinal length (RMSL and LMSL) and the angle of the septal deviation (ASD) and on sagittal plane the height of the PA (PAH), the UAFH and the LM were measured.
Results: There was no difference in PAW, PAH, right and left MSL, UAFH and LM among the groups. Using bivariate correlation, there was no correlation between ASD and PAH, AUFH, LM, RMSL, LMSL, ipsilateral MSL, and contralateral MSL. However, there was weak correlation between ASD and PAW (r = - 0.182, P = 0.044).
Conclusion: The study suggest that nasal septal deviation does not affect PA dimensions, UAFH, and LM.
